1001 is larger than 100, so it has no multiples below 100. Its first multiple is 1,001 itself.
1,001 is greater than 1,000, so its first multiple already sits above that range.
Factors are the mirror image of multiples: they divide into 1001 exactly, rather than being built from it. The factors of 1001 are 1, 7, 11, 13, 77, 91, 143, 1001.
Written as pairs: 1 × 1001, 7 × 143, 11 × 91, 13 × 77.
Broken all the way down into primes, 1001 = 7 × 11 × 13.
The lowest common multiple (LCM) of two numbers is the smallest number that appears in both of their multiplication tables. Here is 1001 paired with the numbers it is most often compared to.
| Pair | LCM | Greatest common factor | Next common multiple |
|---|---|---|---|
| 1001 and 2 | 2,002 | 1 | 4,004 |
| 1001 and 3 | 3,003 | 1 | 6,006 |
| 1001 and 4 | 4,004 | 1 | 8,008 |
| 1001 and 5 | 5,005 | 1 | 10,010 |
| 1001 and 6 | 6,006 | 1 | 12,012 |
Start at 1001 and keep adding 1001. That gives 1001, 2002, 3003, 4004, 5005, and the pattern continues for as long as you want to go. Multiplying is simply a shortcut for the same thing: 1001 × 7 = 7,007 saves you counting seven hops one at a time.
Because 1001 is odd, its multiples alternate between odd and even. That alternation is a quick way to sanity-check an answer before you write it down.
The last digits repeat in a cycle of 10: 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, then back to the start. Spotting that cycle is a fast way to rule out a wrong answer.
The multiples of 1001 are 1001, 2002, 3003, 4004, 5005, 6006, 7007, 8008, 9009, 10010, and so on. Each one is 1001 multiplied by a whole number, so the list continues without end.
1001 is larger than 100, so it has no multiples in that range.
1,001 is greater than 1,000, so its first multiple is already above that range.
The 10th multiple of 1001 is 1001 × 10 = 10,010.
The factors of 1001 are 1, 7, 11, 13, 77, 91, 143, 1001 — 8 in total. Factors divide into 1001; multiples are built out of it.
No. 1001 is a composite number — it has 8 factors, and breaks down into 7 × 11 × 13.
The lowest common multiple of 1001 and 2 is 2,002. It is the first number that appears in both multiplication tables.
